This paper has introduced the composition

basic properties and rheological mechanism of the shear thickening fluid (STF)

factors affecting STF’s rheological mechanism and research methods studying STF’s rheological mechanism are discussed too. Besides

it has explained the preparation of silica and the polyethylene glycol (PEG) / nano-silica particles system in STF

PEG/SiO

2

system’s thickening mechanism has also been commented. Based on the research on STF

this paper has studied the liquid body armor composed of STF-fabric

excellent protective properties

mechanism of bulletproof and stab-resistant (anti-spike

anti-knife) of STF-fabric have been described

besides

the mechanism of stab-resistant of STF-Kevlar has also been introduced. Next

the paper has introduced drop tower testing and quasi-static testing. And the last part of the paper presents a vision on the future research on the liquid body armor.
